M Series Cardio

M3i INDOOR BIKE

More than 20 years ago, Keiser set out to create an exercise bike that would exceed the demands of indoor group cycling: An indoor bike that fits riders of all body shapes and sizes; a bike that achieves a quiet — but true — road bike experience inside your gym or home; and the ONLY stationary bike built in the United States to ensure the tightest quality control. And we accomplished it all with the Simplest of Engineering Designs.

KEISER M3i

VIRTUAL

EXPERIENCE

See how we built the bike through this exciting, interactive experience that guides you through all of the exacting specifications, wows you with exploded views of the bike’s innovative features and enlightens you with the science behind Keiser’s many industry firsts, proving why the M3i truly stands above the rest.

RIDER. OWNER. TECHNICIAN.

DESIGNED AROUND YOU

The Keiser M3i is the industry’s only indoor group cycling bike built entirely around YOU – that’s YOU the rider, YOU the gym owner and YOU the service technician. Game-changing features on the M3i include:

KEISER INDOOR BIKE COMPUTER

ALL THE DATA YOU NEED ON A SINGLE SCREEN

We designed the M3/M3i Indoor Bike computer to be simple, with everything a rider needs to know on a single screen. This includes RPM (Revolutions Per Minute), Power and Energy (Watts and Kilcalories), Heart Rate, Elapsed Time, Gear and Trip Distance. Additionally, the back-lit display turns on when the room light drops below a set level and – unlike other indoor bikes – remains on.

THE BIKER'S DOZEN

Who exactly should an indoor group cycling bike be built for? It shouldn’t be built for riders. Or gym owners. Or maintenance technicians. Rather, a truly great bike should be built for all three. But how can you tell? Download The Biker’s Dozen to find out.

I spent a lot of time on so many indoor bike review websites, I lost count. Some review sites had bikes on their top 10 list that other sites did not and it seemed the reason for that was the reviewer(s) simply don't try every bike. One thing that was consistent however, was the Keiser M3i was at #1 on just about every site. Yes, it's a higher end bike with a higher end price tag. My requirements were magnetic resistance and 4-way seat & handle-bar movement. I could've gotten those two things in a less expensive bike (still around $1300), but that one didn't include a floor mat nor the Bluetooth computer, which I also wanted. Here's the bottom line...if you want to be able to ride/train when the weather is bad or you just want a 30 minute spin whenever you feel like...
